  1. *p-values obtained by paired t-test.
  2. The anatomic depiction of neural anatomy was scored on a 5 point scale (1 = not visible, 2 = just visible, 3 = patchy visibility and/or not contiguous with adjacent segments, 4 = mostly visible but not fully traceable into contiguous segments, 5 = clearly visible and traceable into contiguous segments).
